NP in Pain Management Specialty: Any NPs in pain?

Hi, everyone! I'm new here.

I'm just wondering if NPs can specialize in pain management? If so, is there some kind of certification or credential?

What generally is an NPs scope of practice in pain management? Do they do a lot of med management?

What kinds of settings can they work in? Can they work in both inpatient (surgical, oncology, etc) or just outpatient chronic pain clinics?


What kind of NP would be appropriate for this position: FNP, ACNP, ANP, etc?

What kind of pay can an NP expect in pain management for both inpatient and outpatient?

If anybody can answer these questions or if anybody here is an NP in PM, it would be greatly appreciated!
Thank you!
